#add_to_index provides a way to add files to the repository's index

#create_commit creates a commit off the state of the repository's index

The flow of using the RepositoryHelper is:

 create_repository

 add_to_index  // This can happen many times per commit
 create_commit // Add many commits by repeating #add_to_index and this

 delete_repository
